fa عمومى General كاربردي Applicable <strong>Background: </strong>The present study investigated the effect of a 4-week training with Total Resistance Exercises (TRX) on performance and balance in healthy children.<br> <strong>Methods</strong>: In total, 26 children aged 12-16 years were purposefully selected. Then, the study subjects were randomly divided into two groups of TRX (n=13) and control (n=13). The static and dynamic balance and performance were measured by Sharpened Romberg Test, Y Balance Test, and Functional Movement Screen (FMS), respectively. The experimental group performed TRX for 4 weeks; three 55-minute sessions per week. The obtained data were analyzed using statistical tests, including t-test and Analysis of Covariance (ANCOVA) in SPSS.<br> <strong>Results: </strong>The t-test results suggested a significant difference between the pretest-posttest scores of all variables assessed in the experimental group (P&le;0<span dir="RTL">.</span>05). In addition, ANCOVA results indicated that performing TRX significantly improved the balance and FMS score in the experimental group, compared to the controls (P&le;0<span dir="RTL">.</span>05).<br> <strong>Conclusion:</strong> Conducting 4 weeks of TRX training significantly improved static and dynamic balance and FMS values in healthy children; therefore, coaches can use these exercises to improve balance and performance and prevent injury in this group.
